HENRY D. CONWAY, OF DETROIT, MICHIGAN.

FLOOR .AND CEILING CONSTRUCTION.

Application led September 1, 1920..Y Serial No. I07,4270.

To all whom it may concern.'

Be it known that I. HENRY D. CONWAY, a citizen of the United States,residing at Detroit, county of lVayne, State of Michigan, have inventedcertain new and useful Improvements i-n- Floor and Ceiling 'Constructions, of which the following is a specij fication.

This 'invention relates to improvements in floor and ceilingconstructions.

The main objects 'of this invention are:

First, to provide in Hoor and ceiling constructions an improved metaltile member or unit which may be easily assembled in spaced rows asdesired and the bottoms of which constitute lathing units.

Second, to provide an improved metal tile member for floor and ceilingconstructions which is very economicalto produce and is easily assembledor arranged in position to receive the concrete.

Further objects, and objects relating to structural details willdefinitel appear from the detailed description to fol ow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. VThe invention 1s clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment-of my inventionis ,clearlyillustrated in .the accompanying drawing forming a part of thisspecification, in which:

Fig. I is a plan view of a row or series of m improved tile members orunits in assemb ed relation.

Fig. IA is a bottom view of one of the tile members or units.

Fig. II is a verticaltransverse section through one of the units on aline correspondlng to line 2-2 of Fig. I.

Fig. III is an inside perspective view of one of the end members.

Fig. IV is a plan view of the sheet metal blank from which my improvedtile members are formed.

- Fig. V is a detail perspective view of a floor and ceilingconstruction illustrating the method of usin the same and also therelation of the ti e members in the completed structure.

Fig. VI is a detail vertical section through the completed structureillustrating the lathingI feature of my improvements.

ig. VII is an inverted detail view of the ceiling prior to theapplication of the A plaster. j

In the drawing similar reference characseveral views.

Referring to the drawing, I provide a plurality of sheet metal tilemembers or units designated generally by the numeral 1, each having atop 2, sides 3 and 3 and bottom 4.

ltersrefer to similar parts throughout the These uits are preferablyformed of an integral .folded blank ofsheet metal as shown 1n Fig. IV,the folding points being indicated by the dotted lines.

i Une end of the blank constitutes the bottom 4 and the other the side 3which ter- 70 adjusted position or assembled relation in,

the construction to receive the concrete.

The bottom 4 has portions 8 struck up therefrom so that the bottomvofeach tile member constitutes a lathing unit to receive plaster in thecompleted structure.- The .members are arranged in rows with` their endsin telescoping engagement to permittelescoping without the necessity forvaryin the diameters of the several units.` One en of the bottom of eachmember is slotted at 9 adjacent its ,side wall to receive the edfres ofthe side walls of the member tele.

scoped therewith.

The flanges 5 are also cut away at one end at 10 so that the flange ofthe member telescoped therewith may telescope with the projecting end 11of the portion 6 embraced by the flange 5. I also provide end closures12 having flanges 12 at the top and sides thereof adapted to telescopewith the ends of the tile members so that the ends of a row of the tilemembers may` be conveniently closed- In Figs. V, VI and VII, Iillustrate one method of using my improved tile members. The false workor supportsl are ar- -ranged in suitable spaced relation so that Ifdesired to provide bridging between they beams, the members are spacedin the rows as shown at 14, the closures l2 being provided at thispoint. The concrete 15 is poured or spread over and between these tilemembers forming the floor and its beams. The sides of the tile membersare indented at 16 so that the tile members are firmly supported in theconcrete. The false work'13 is then removed, the nails 7 being cut offbelow the flanges,l and the plaster 17 may be applied as indicated, theplaster being effectively supported by the tile membersv and the exposedportion of the beams to which it will effectivelyadhere.

The units of my improved floor and ceiling construction are veryeconomical to pro` `duce, may be rapidly and easily assembled in thestructure, and the false work or supports quickly removed, and whenremoved, the structure is ready for the plaster or coating y I have usedthe term tile herein as suchterm is quite generally used by the buildingtrade although the term domes and other terms are also used to designatethese devices.

I have illustrated and described my improvements without special regardto the proportionof parts and more or less 1n conventional form as theportions may be greatly varied and will no doubt be considerably variedin adaptations to particular work or requirements. I believe, however,that the disclosure made will enable those skilled in the art to whichmy invention relates to embody or adapt the same as may be desired.

vHaving thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A metal tile member for floor and ceiling structures comprisingiatop, sides and bottom formed of an integral folded blank of sheet metal,one end of which constitutes the bottom and the other aside terminatingin an outwardly projecting flange folded upon itself and embracing thefree edge of the bottom and constituting an attaching flange, the bottombeing slotted at one end adjacent the sides to receive the edges of thesides of a coacting tile member telescoped therewith, the bottom havingportions struck up therefrom whereby it constitutes a lathing unit.

2. A tile member for floor and ceiling structures comprising a top,sides and bottom formed of an integral folded blank, the bottom beingslotted -at one end to receive the edges of the sides of a coacting tilemember telescoping therewith, the bottom being foraminated whereby itconstitutes a lathing unit.

3. A sheet metal tile member for floor and ceiling structures comprisinga top, sides and a foraminated bottom constituting-a longitudinal edgeadapted for attachment to a support, said members being disposed inspaced rows with their ends in telescoping engagement, their bottomsbeing slotted at one end to receive the edges of the sides of a coactingmember telescoped therewith.

5. A metal tile member for floor and ceiling structures comprising atop, sides and bottom formed of an integral folded blank of sheet metal,one end of which constitutes the bottom and the other a side terminatingin an outwardly projecting flange folded upon itself and embracing thefree edge of the bottom providing a. horizontal flange disposed in theplane of the bottom and adapted for attachment to a supporting form orfalse work upon which the tile member is resting.

6. A sheet metal tile member for floor and ceiling structures comprisingtop, sides and bottom. the bottom being slotted at one end to receivethe edges of a coacting member telescoped therewith.

7. A floor and ceiling construction com-- prising tile members eachhaving-a top, sides and a foraminated bottom, the face of the bottombeing free from projections permitting plastering directly thereon, thebottoms of said tile members being slotted at one end to receive theedges ofthe sides of a coacting tile member telescoped therewith.
